# Is the HTTP QUERY method safe, idempotent, and cacheable according to the HTTP specification?

## Is the HTTP QUERY method safe, idempotent, and cacheable according to the HTTP specification?

## Answers

### Answer by Anubhav Sharma

Yes. According to the HTTP specification for the newly standardized [**QUERY** method (RFC 10008)](https://www.rfc-editor.org/info/rfc10008/), the **QUERY** method is:

- **Safe:** **Yes** — A [QUERY request](https://www.rfc-editor.org/rfc/rfc10008.html) is defined as a safe method, meaning it does not request or expect changes to the state of the target resource. Servers may still perform incidental actions such as logging, but the resource itself is not intended to be modified.
- **Idempotent:** **Yes** — Sending the same [QUERY request](https://www.rfc-editor.org/info/rfc10008/) multiple times has the same intended effect as sending it once. This allows clients to automatically retry requests after connection failures without risking unintended state changes.
- **Cacheable:** **Yes** — Responses to QUERY requests are explicitly cacheable. Unlike GET, however, caches **must** include the request body (and related metadata) as part of the cache key, since the body determines the query being executed.

| Property | QUERY |
| --- | --- |
| Safe | Yes |
| Idempotent | Yes |
| Cacheable | Yes |

The motivation behind QUERY is to provide a method that combines the benefits of **GET** and **POST**:

- Like **POST**, it carries a request body, making it suitable for complex or large query parameters.
- Like **GET**, it is **safe**, **idempotent**, and **cacheable**, enabling automatic retries and efficient caching.
